Three Point Bending

In this lab, a three-Point Bend test is performed on a round rod. The distance between the anvils is varied, and the resulting effect on the stiffness of the beam is measured. A graph of the resulting data yields the Flexural Elastic Modulus for the material.

Set of three each of 1/8" diameter aluminum, brass, and mild steel samples.

Bending Accessory

Perform three-point bending tests of various metals.

Materials Testing Machine

Materials Testing Machine

This is the assembly-only version; measures force and displacement for various materials as the materials are stretched, compressed, sheared, or bent.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
